Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 

Temperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation

Noncontact infrared temperature sensors absorb ambient infrared (IR) radiation given off by a heated surface. They are used in applications where direct temperature measurement is not possible

Temperature indicators and temperature instruments are designed for temperature monitoring and analysis. These devices either come equipped with an integral sensor, or require sensor input

RTD (resistive temperature device) elements are wire windings or other thin-film serpentines that exhibit changes in resistance with changes in temperature

Temperature probes are used in various temperature sensing applications. Technology options include thermocouple, RTD, thermistor and solid state style probes

Thermistors are thermally-sensitive devices whose electrical resistance varies with temperature. Unlike RTDs and thermocouples, thermistors do not have standards associated with their resistance vs. temperature characteristics or curves

RTD temperature probes convert the RTD resistance measurement to a current signal, eliminating the problems inherent in RTD signal transmission via lead resistance. 

Environmental test chambers and rooms are used to ensure the reliability of industrial products, especially electronic items, through prolonged exposure to one or more environmental parameters.

Temperature signal conditioners accept outputs from temperature measurement devices such as resistance temperature detectors (RTDs), thermocouples, and thermistors. They then filter, amplify, and/or convert these outputs to digital signals, or to levels suitable for digitization

Thermistor temperature probes sense temperature by using thermistors, devices made of semiconductor materials which exhibit a large change in resistance for a small change in temperature

Resistance temperature detector (RTD) temperature transmitters convert RTD resistance measurements to current signals, eliminating the problems inherent in RTD signal transmission via lead resistance

Humidity measurement instruments test for absolute humidity, relative humidity, or dew point in air

Material testing services test, analyze, and certify a wide range of materials for purity, chemical compatibility, and environmental impact.

Temperature sensor chips are semiconductor dies or packages that have built-in temperature sensors
